Yeah, the full strategic realistic picture of the battle you couldn't really capture, but how about a phase of the battle such as the breakout to Lisyanka? (see attached map)

With regards to East Front III, I think its a great, noble, and wonderful endeavor to further the legacy of the Greatest Game Ever Created by Mankind. I've consistently played EF since 97' and its my all-time favorite. Perfectly Squad-Leaderesque. My understanding was that III would be the exact same game but with a revamped and much improved design engine. Great! But no need to mess with the graphics and basic design flow I hope.
We wish them well and hope it turns out to be a killer game!
